Tom Clancy's Splinter Cell: Endgame is the sixth novel in the Splinter Cell novel series. Like all the others it was published under the pseudonym David Michaels. Endgame is a retelling of Tom Clancy's Splinter Cell: Conviction (novel) from the pursuing group's point-of-view. It is also suggested that this may be the last novel.

The first thirteen chapters of Endgame (one-third of the book) take place before the first chapter of the Conviction novel, over the course of approximately 18 months (switching between the past (18 months ago) and the "present"). A few sections of the last chapter and epilogue goes beyond events of the Conviction novel.

Endgame leaves one of the primarily villains, Allen Ames alive and uncaptured. He is last shown making deals with terrorists. Leaving him open for a future novel (if Ubisoft decides to publish another).
